Spontaneous regression of two putative supratentorial haemangioblastomas in one patient.

Supratentorial haemangioblastomas are exceedingly rare lesions. We report a patient with spontaneous regression of two suspected supratentorial haemangioblastomas after removal of one lesion. The patient was a 61-year-old man who had a generalised seizure. Investigation with MRI revealed three supratentorial lesions situated in the trigone, occipital and frontal locations. The lesion in the occipital area was surgically removed and the histopathology was consistent with a haemangioblastoma. MRI investigations performed 6 months and one year after the operation confirmed that the two remaining lesions had totally disappeared.
